Fine. I have added a ticket https://phabricator.wikimedia.org/T118322 "Merging wizard shouldn't allow dissimilar items to be merged". Perhaps a developer can help solve the issue.

You misunderstand me if you thought I was blaming Magnus for this.  It
was a hypothesis that right now seems false and we do not yet have
another answer.  I do think it is entirely possible that a high-volume,
low-user-expertise game interface could generate problems very much like
what we are observing.  I think we should be able to track them more
transparently than we can now.
The widar tag seems a starting point:
https://www.wikidata.org/w/index.php?title=Special:RecentChanges&tagfilter=OAuth+CID%3A+93
but this could be improved.

p.s. Side note on the game.  Other very similar things usually
incorporate some level of redundancy - e.g. you show the same thing to
multiple people and only keep statements where 2 or more people agree..
Lower recall but higher precision - depends on the goal.

    If I understand correctly:

    1) Magnus' game already tags the edits with 'Widar'.

    2) Magnus' game cannot merge protein and genes if they link to each
    other. With 'ortholog' and 'expressed by' Magnus' merging game does
    not contribute to the problematic merges (Magnus email from
    previously today: "FWIW, checked again. Neither game can merge two
    items that link to each other. So, if the protein is "expressed by"
    the gene, that pair will not even be suggested.").

    There is nothing more that Magnus can do, - except making an
    unmerging game. :-)

        In another thread, we are discussing the preponderance of
        problematic
        merges of gene/protein items.  One of the hypotheses raised to
        explain
        the volume and nature of these merges (which are often by fairly
        inexperienced editors and/or people that seem to only do merges) was
        that they were coming from the wikidata game.  It seems to me that
        anything like the wikidata game that has the potential to generate a
        very large volume of edits - especially from new editors - ought
        to tag
        its contributions so that they can easily be tracked by the
        system.  It
        should be easy to answer the question of whether an edit came
        from that
        game (or any of what I hope to be many of its descendants).
        This will
        make it possible to debug what could potentially be large swathes of
        problems and to make it straightforward to 'reward' game/other
        developers with information about the volume of the edits that
        they have
        enabled directly from the system (as opposed to their own
        tracking data).

        Please don't misunderstand me.  I am a big fan of the wikidata
        game and
        actually am pushing for our group to make a bio-specific version
        of it
        that will build on that code.  I see a great potential here - but
        because of the potential scale of edits this could quickly
        generate, we
        (the whole wikidata community) need ways to keep an eye on what
        is going
        on.
